why doesn't gf just move the pilots to the embraer starting with the most junior captains and junior first officers? it would be fair not to make them sign new bonds since that type rating would be next to useless outside sao paulo. it would serve to weed out guys who are unhappy and decide to resign which gf will need to know for crew planning purposes. the void left by them, most lost likely from the 320 fleet, will be filled by those up the seniority list.
